Also, watch her great film, "Sita Sings the Blues": https://archive.org/details/Sita_Sings_the_Blues
And then read all about how restrictive, bloated copyright on almost century-old music stifled her creativity and distribution options for this film:

And since I have you all here already, do watch "Good Copy Bad Copy": https://en.wikipedia.org/wiki/Good_Copy_Bad_Copy

Seriously, get informed about copyright in the digital era. It affects us all, for better or worse.
